WARP-BEAMING MACHINE.

SPECIFICATION forming part of Letters Patent No. 581,299, dated April 27, 1897. Application filed September 21, 1896- Serial No. 606,475. (No model.)

r0 all whom it may concern:

Be it known that I, DAVID MGTAGGART, a citizen of the United States, residing at \Vorcester, in the county of WVorcester and State of Massachusetts, have invented a new and useful Improvement in Warp-Beaming Machines, of which the following is a specification, accompanied by drawings represent ing so much of a warp-beaming machine embodying mypresent improvement as is necessary to clearly illustrate the nature of my invention and the manner in which the same is carried into effect.

Referring to the accompanying drawings, Figure 1 represents a front View of a warpbeaming machine embodying my invention. Fig. 2 represents in perspective viewawarpbeaming machine embodying my invention, the mechanism by which the warp-beam is rotated having been omitted. Fig. 3 is a perspective view of my improved warp-beaming machine shown in perspective View, but with the pressure-roll in an elevated position. Fig. 4 is a central longitudinal sectional view of the pressure-roll. Fig. 5 is a transverse sectional view of the pressure-roll and the central hooked arm of the framework by which the pressure roll is supported, said section being taken on a vertical plane passing through the center of the central hooked arm of the framework. Fig.6 is an end view of the pressure-roll and a portion of the supportingframework, showing the latch by which the pressure-roll is held from longitudinal movement in one direction when raised in the position shown in Fig. 3. Fig. 7 is a central sectional view of the screw-actuated sliding block with which the suspension-rope is connected, the section being shown on line 7 7, Fig. 8. Fig. 8 is a side view of the screwactuated sliding block shown in sectional view in Fig. 7, and Fig. 9 is a perspective view of the flanged sleeve by which the free end of the pressure-roll-supporting frame is locked in one of the supporting-stands.

Similar letters refer to similar parts in the different figures.

In Figs. 1, 2, and 3 of the accompanying drawings I have represented the warp-beam and the pressure-roll with its supportingframe as resting upon the upright stands A A A of the simplest form of construction,

but in the place of these stands any suitable framework can be employed to support the operating parts of the machine.

B denotes a warp-beam'journaled in the stands A and arranged to be slowly rotated by any of the well-known mechanisms em-' ployed for that purpose, one of which is represented in Fig. 1, and consisting of a supporting-framework C, in which is-journaled a shaft 0, carrying a belt-pulley C by which power is applied to the shaft, and a pinion C engaging a gear C upon a shaft C to which is attached a pinion C engaging a gear O attached to the warp-beam B.

As the warp-beam B-is slowly rotated the warp-threads are drawn from areel (not shown) and wound upon the barrel B of the warp-beam and between the heads B B in the usual and well-known manner.

At the side of the warp-beam is a rocking bar D, supported upon the upright stands A A or other suitable framework and held parallel with the axis of the warp-beam B. The bar D is so held in its supporting-stand as to be capable of rocking freely and also of being raised into an elevated position, as shown in Fig. 3, with one end raised clear from one of the supporting-stands, while the opposite end is held in the other stand,and I accomplish this as follows: One end of the rocking barD terminates in a ball D, held in a circular socket D formed on the upper end of the stand A. The opposite end of the rocking bar D is provided with a circular journal D3, inclosed by a flanged sleeve D which is held when the machine is in operation in the upper end of the upright stand A The stand A is provided with a circular hole D of the same diameter as the outer diameter of the sleeve D,

with an opening D of the diameter of the journal D so that when the journal D is dropped from the position shown in Fig. 3 through the opening D and the sleeveD is moved lengthwise on the journal and inserted in the circular hole D the rocking bar D will become locked in a horizontal position in the stand A but be capable of rotating freely within the sleeve D and socket D Attached to the rockiu g bar D are the arms E E and central-arm E extending over the barrel of the warp-beam and provided with hooked ends E adapted to inclose about twothirds of the periphery of a pressure-roll F, which is inserted cndwise within the hooked ends E of the arms, so as to be held parallel with the axis of the barrel B of the warpbeam with its under side resting upon the barrel B or upon the warp-threads as they are wound thereon. Each of the arms E E E are recessed at their hooked ends, as shown at E, to receive the friction-rolls E, which turn upon pins E, held within the arms E E E The friction-rolls E are arranged to bear against the periphery of the pressureroll F, so as to reduce the friction upon the pressure-roll and permit it to be rotated within the hooked ends of the arms by its frietional contact with the rotating warp-beam.

Above the central arm E is a bar G, jonr naled in the arm G, projecting upwardly from the central arm E and in an arm G attached to the rocking bar D. The edges G of the bar G form ways for a slidin block G which is traversed along the bar G by means of a rotating screw G journaled concentrically within the ends of the bar G and connected with the sliding block G by means of a screw or pin G, held in the block G and engaging the threads of the screw.

The sliding block G carries studs G upon which are placed the friction'rolls G ,arrangcd to bear against the lower edge G of the bar G, and the upper end of the block G is provided with a circular socket to receive a ball G, forming a balland-socket joint.

Rigidly attached to the ball G by a neck G is a pulley-block G containing a pulley G to receive a wire cable G The wire cable G has one end attached to the ceiling and passes around the pulley G and over a pulley i suspended by a swiveljoint from the ceiling, and from the end of the wire cable I suspend the weights G so as to exert a lifting strain upon the bar G and connected framework carrying the pressureroll F.

When the rocking bar D is held within the stands A A by a ball-andsocket joint at one end and by a flanged sleeve D at the opposite end, the strain exerted by the weights G will tend to rock the bar D and carry the pressure-roll F toward oraway from the warpbeam, as determined by the position of the sliding block G with reference to the vertical plane passing through the axis of the rocking bar D. For example, if the sliding block G be moved along the bar G by the actuating screw G to a position to the right of the vertical plane passing through the axis of the rocking bar D and opposite to the warp-beam, as represented in Figs. 1 and 5, then the weights G will tend to rock the bar G and increase the pressure of the roll F upon the warp as it is wound upon the warp-beam; but if the sliding block G is moved upon the same side of the rocking bar D as the warpbeam it will tend to rotate the rocking bar D in the opposite direction and lift the pressure-roll F oii the warp. The amount of pressure exerted upon the warp can therefore be varied by shifting the position of the sliding block G along the bar G by rotation of the screw G by means of a wrench or crank applied to the squared end G of the screw.

\Vhen the warp-beam has been filled, the flanged sleeve D is withdrawn from the circular opening D in the stand A and the sliding block G is moved along the bar Gtoward the 'n'essure-roll F, causing the weights G to raise the end of the rocking bar D through the opening D in the stand A lifting the pressure-roll F into the position represented in Fig. 3, thereby allowing free access to the warp-beam. When the pressure-roll is raised in an oblique position, as represented in Fig. 3, it is prevented from sliding en dwise through the hooked endsof the arms E E E bymeans of a latch consisting of a plate II, pivoted at one end to the side of the arm E and carrying at its opposite end a projecting rod II, to which is adjustably attached an arm H arranged to drop over the end of the pressureroll E and hold itagainst gravity. Attached to the arm E isa plate II, provided with a slot II, through which the rod ll passes and serves as a guide for the free end of the pivoted plate II.

IVhen the bar D is lowered into the position shown in Fig. 2, the pressure-roll F will lie upon the barrel B of the warp-beam, filling the space between the heads B B and the lower end of the arm II will rest upon and be held up by the head of the warp-beam.

The pressure-roll F is variable in length, in order to allow for any irregularity in the space between the heads 13 B of the warp-beam, and it is also made in sections to allow its length to be adjusted approximately to the length of different warp-beams. The construction of the pressure-roll F is shown in central sectional view in Fig. i of the accompanying drawings, where I denotes the central portion of the roll, having at one end an extension-piece I, detachably attached to the central portion by a screw 1 allowing the extension-piece I to be exchanged for others of dilierent lengths, in order to adapt the pressure-roll to different warp-beams. At the opposite end of the pressure-roll is a spring-actuated sliding section J, provided with a concentric hole J at one end fitting upon and sliding over the reduced end J 2 of the central portion I.

The section J is acted upon by a spring or springs inserted between the end of the section J and the shoulder J on the section I.

In the construction shown in Fig. 4 I employ two springs J 4 and J separated by an annular collar J G midway between the end of the section J and the shoulder J and to the outer surface of the collar J I attach the thin sleeve J with its ends overlapping the sections J and I, so as to cover the chamber containing the springs J and J 5 and form a continuous surface. The sliding section J is held upon the section I and against the action of the springs J 4 J by means of a screwJ which is screwed into the reduced end J 2 of the section I and is provided with a projecting flange J bearing against the recessed end of the sliding section J. The sliding movement of the section J is limited in the opposite direction by means of an annular plate J at tached to a shoulder J in the recessed end of the section J, allowing a limited movement of the section J equal to the distance between the annular plate J and the flange J a fraction of an inch being usually sufficient to allow for the usual variation in the distance between the heads 13 B upon opposite ends of the warp-beam. The screw J 3 .is provided with a squared end J projecting through the annular plate J to receive a wrench and allow the length of the warp-beam to be varied by screwing or unscrewing the screw J The operation of my improved warp-beaming machine is as follows: The warp-beam to be wound is placed in position, as represented in Fig. 3. ing bar D and arms E, E, and E supporting the pressure-roll F within their hooked ends, is then lowered from the elevated position shown in Fig. 3 to the horizontal position represented in Figs. 1 and 2, the end D of the rocking bar D being locked within the stand A by means of the sliding flanged sleeve D in the manner already described. The sliding block G is then moved from the position shown in Fig. 3 to that shown in Fig. 2, so the strain of the weight G will be exerted to rock the bar D and carry the pressure-roll F down upon the warp as it is being wound upon the warpbeam the pressure being increased as the sliding block G4 is moved farther to the rear of the rocking bar D. The pressure roll F, when in the elevated position represented in Fig. 3, is held from being moved lengthwise within the frame by gravity by means of the latch, consisting of the pivoted plate H, rod 11, and arm H said arm overlapping the end of the roll, as represented in Fig. 6. Vhen the roll F is lowered into the position shown in Figs. 1 and 2 an d inserted between the heads of the warp-beam, the arm H rests upon the edge of the warp-beam head, lifting the pivoted plate H, allowing the pressure-roll to drop upon the barrel of the warp-beam, filling the space between the heads. As the warpbeam rotates the space between the heads is liable to vary slightly, owing to the heads not standing in parallel planes at right angles to the axis of the warp-beam, and this variation in the distance between the heads of the warpbeam is provided for by means of the sliding section J, which is crowded against the inner side of the warp-beam head by the action of the springs J 4 J 5 and allows a slight contraction in the length of the warp-beam to correspond with the variation in the distance between the inner sides of the heads. As the warp-beam is filled the pressure-roll F rises, rocking the bar D in the stands A A The frame, consisting of the rock-- lVhen the operation of winding is com-- pleted, the sliding block G is moved forward of the rocking bar D or upon the same side as the pressure-roll F by means of the screw G", as shown in Fig. 3. The rocking bar D is released from the stand A by sliding the flanged collar D" out of the opening D and allowing the end D of the rocking bar D to be lifted through the opening D into the position represented in Fig. 3, allowing free access to the warpbeam.
